"I have not retired," Wallace told the Des Moines Register. "I have just removed myself from the San Francisco situation because it wasn't a perfect fit for me."

Wallace's agent, Don Yee, met with Jim Harbaugh on Thursday morning and told the 49ers coach that the quarterback didn't want to play against the Chargers if it was in a mop-up role that could jeopardize his health, according to The Sacramento Bee.

"For him to come out and say that, 'Hey, Seneca's planning on his retirement' ... I don't think that's even 100 percent fair for him to come out and say that because I don't even know him," Wallace told the Register. "I think that should be my decision."
